[khilari]

Hi guys, i wanted to ask that if i am running on 11 vi why would i want to switch to 11 vi2 or 11vi3......

EOS -> End of Support

Much more functionality! 11iv3 has a significantly better i/o stack. Native multipathing, persistent device names, better performance.

Read the release notes for each release to make your own determination.

However, this presumes that your application(s) are supported on the newer releases.

Also be aware the v2 and v3 may not necessarily run on your hardware. Be sure to check that before contemplating an upgrade.

Hi

11.11 will be supported til 2013.

11.23 is transitional the way 10.30 was transitional.

11.31 has many differences

PA-risc is supported in a minor way. Many applications are forced to use a Pa-Risc emmulator called Aries.

Kernel Parm.s are very different

Native Multipathing is used instead of PV links

SD-UX goes away and SWA is now the patching method.

IA64 virtual machines are very different from vpars and npars.

Because you have virtual machines crash dumps are different.

You have the ability to upgrade some servers from Pa-Risc to Ia64. I.e, rp8420 to rx8620.

Note: I've been pretty steady into 11.31 for 6 months now and still making discoverys.

Hi again

diagnostics are very different in 11.31, somewhat different in 11.23.

Hello again

Here are the Sept 2009 release notes for 11.31, refer to the "What's New" sections.

> PA-risc is supported in a minor way.

Huh? Minor? What's minor about it?

Well, yeah, _if_ you replace your PA-RISC
system with an IA64 system. Are you saying
that that's required?

[Wim Rombauts]

Maybe, let's revert the question.
Why stay on 11i v1 ?
-> If your server and the applications on it are running fine, and there are no new implementations at hand, there is no real reason to upgrade.
Yes, you will have newer and better technology in your hands when you upgrade, but if everything is running fine now, you don't really need it. The year 2013 (EOS for 11i v1) is still a lot of year away.

But, if you are planning to upgrade the hardware, if you are planning a major upgrade of the software, if you need (or want)to implement new things that may be easier to do on HP-UX 11i v3, or not possible on 1&i v1, yes, then upgrade. It will be worth it.

> Michael: 11.23 is transitional the way 10.30 was transitional.

Not sure what you mean by that?
10.30 was for special customers. 11.23 is for general release.

[Michael Steele_2]

Dennis,

What was the same between 10.20 and 10.30? They were both transitional.

What was the difference? Probably the extra telephone network stuff like X.25.

When at ATT, we used 10.30 on maybe 3,000 servers.

Steven,

Sigh. You really need to work on your tedious attitude. Maybe you don't realize it, but its a personal problem that you were recently called on by another forum user. So I take that back, you are aware of it but do it anyway, for here you are again doing the same thing in what, only 7 days?

11.31 was orginally marked exclusive to Itanium. But like many things in 11.31, that changed. Hyperthreading for example. First advertised as supported in 2008, later advertised as not supported in 2009. Probably a lot of Pa-Risc people objected. I only read the release notes.
